In the drawings: y j Fig. 1 1s an elevation looking` at the inside f "*of a side rail and its connectiontoa bedstcad end Vframe corner post.

Fig. 2 is'also an elevation of'` the 'insideV of the side rail lock, looking towards lthe end frame, and Fig. 3 is a section on the line 3&3 A0"ofFig.l. l

. Referring Anow to. the drawings, I vhave shown a corner post 5 and a side railv 6 which A constitute parts of a kbedstead construction, the-corner post 5 being preferably a part of fian' endf'fraine in accordance with well'known practice. Vf'lVIyimproved connection between .the side Y rail andl corner post or end frame'includesy a Y 1 ,bracket or` flange plate 7 which' is secure-d to 46"'thecorner'post by suitable 'meanssuch as one or .more screws 8. The bracket plate 7 is preferably recessed in they corner post as iny dicated in Fig. '3. Another bracket, which' may consistof a simple angle ironrnemben is 'secured tothe side rail 6.. One-.flange 10 of the bracket is seated againstu and secured 'to' the inside face, of the side rail and preferably in a recess provided therein, by suitable means such as'screws 11. The other leg or y50 flange' 12 of the bracket 9 extends laterally inrARRY; sa.; or Y"irElvosHiu WISCONSIN,fA'ssIGNoiajroSIMMONS. CQMPANY "or xENosHA, W1scoNs1N,.A ooBBoRATIo'NgoF,.wisconsin .Y

For positioning fthe side-,rail with respect 5g.. to'thegcornerpostor' end frame, I provide I y the flanges 7 or 12 with inte'rfitting,l means;4

Forloclin'githe flangesftogether so to prevent'lateral separationv thereof, I provide a screw 15 which is anchored to the llange'f',

i Obviously, the

cidental unlocking of the connection is thereby effectively prevented. As clearly shown in Fig. 2, the clamping device is located to one side of the plane of vertical alignment of the inter-connecting dowels. By so locating the clamping device, the spacing'shoulders 19 on the respective dowels serve as fulcrum points about which the clamping device tends to rock the flange 12 horizontally relative to the flange 7, thereby eecting tight engagement between the end of theside railV 6 and the adjacent face of the corner post 5.

It will be seen that the above described connection is effective to lock the side rail 6 to the corner post 5 with the end 20 of the side rail in tight engagement withthe adjacent face of the corner post. `LThe clamping nut, being` a wing nut, affords, in effect, a lever arm arrangement whereby the nut is manually releasable or engageable in spite of the resistance to its adjustment due to the resiliency and yielding of the bracket flange 12.k v

described connecting means may be effectively mounted `without recessing either of the bracket parts, it being merely necessary to cause the end 2O of the side rail to project beyond the flange 12 a distance substantially equal to the combined thickness of the bracket plate 7 and the width of the space between the flanges 7 and 12. @ther changes and re-arrangements of the above described structure may also be made without departing from the spirit of my invention, the scope of which should be determined by reference to the following claims,

construing the same as broadly as possible consistent with the state of the art.

I claim as my invention: y

1. In a bedstead, the combinationofl an end frame,a sidejrail, and means for detachably connecting said end frame and side rail comprising a bracket carried by said end.

frame, a bracket carried by said side rail, said brackets having mutually overlapping flangeportions, and being provided with' spaced, interfitting dowel means for relatively positioningthe parts, .shoulders on said-` same apart adjacent their inner edges, said brackets being also provided with means for interlocking the same in predetermined relative position, and means spaced outwardly from said spacing means for clamping said parts together, said clamping means serving, in effect, to rock said parts relative to each other about said spacing means as a fulcrum, thereby to effect tight engagement between the end of said side .rail and said end frame.

3. In a bedstead, the combination of an end frame, a side rail normally having one end abutting said end frame, and means for detachably connecting said end frame and side rail comprising a bracket carried by said end frame, a bracket carried by said side rail, said brackets having mutually overlapping flange portions and being provided with spaced, inter-fitting dowel means adjacent their inner edges, said dowel means serving to position said flanges relative to each other andbeing provided with shoulders for spacing the flanges apart adjacent said inner edges, and lclamping means intermediate said dowel means and disposed outwardly thereof for locking said flanges together, said clamping means tending to rock said flanges toward each other about said spacing shoulders as fulcrum points, thereby to effect tight engagement of the end of said side rail with said end frame.

dowel means for maintaining said flanges 'j in spaced relation to each other, and clamping means intermediate said dowel means for locking said flanges together, one of said flanges being sufficiently resilient to yield under the pressure of said clamping means, the resiliency of said part servingto maintain said clamping means in operative position.

2. In a bedstead, the combination of an end frameya side rail normally disposed with one end abutting said end frame, and

means for detachably connecting said parts comprising a pair of brackets respectively carried by said end frame and side rail, said brackets extending inwardly from said side rail and including mutually overlapping parts `provided with means for spacing-the
